LSP Composite Susbtrate Manufacturing Processing Guide

Manufacturing procedures to fabricate protected and unprotected Carbon Fiber Reinforced Plastic (CFRP) test panel configurations that can be employed for the purposes of evaluating the protection capabilities of Lightning Strike Protection (LSP) materials are documented in National Aeronautics and Space Administration (NASA) DOC-128694. The composite test panels are intended to provide consistent behavior in their response to simulated lightning strikes at pre-defined levels when tested by a capable vendor according to a test procedure written to enable consistent results. It is expected that commercial vendors of existing and emerging LSP materials and concepts would use the behavior of this protected configuration as a baseline performance standard which they would try to meet or exceed. The unprotected configuration consists of a cured CFRP laminate of tape (Hexcel HexPly 8552/AS4) and fabric (Hexcel HexPly 8552 / A193-PW, 3K-70-PW) prepregs, coated with a typical aerospace primer (0.5-1.5 mils thick) and paint (4-6 mils thick) finishing scheme. The protected configuration contains a top LSP layer made up of Cytec Surfacemaster 905C Composite Surfacing Film above Dexmet 3CU7-100FA expanded copper foil and is included in the laminate stackup prior to cure.
